Abstract: A windshield wiper arm including a rear end segment fixed to a shaft driving the windshield wiper arm in an alternating wiping movement about the global and vertical axis, a free front segment for supporting a wiper blade, and an intermediate segment with a longitudinal orientation which is at least partly elastically deformable and which links the rear end segment to the free front segment, wherein the intermediate segment includes a longitudinal central web which is covered with an outer sleeve, wherein at least one portion of the longitudinal central web includes a multilayer plate made of globally horizontal superimposed layers of different materials and thickness, and wherein the multilayer plate comprises at least one layer made of a composite material.

Abstract: The invention concerns an arrangement for mounting a single-piece windscreen wiper arm (10) on a head (12) driving the arm (10) in a reciprocating sweeping movement, wherein the arm (10) comprises a first mounting end (10a) which is connected to the driving head (12) so as to transmit the sweeping forces driving the arm (10) and wherein the first end (10a) of the arm (10) is mounted mobile relative to the driving head (12) between a lowered wiping position wherein the blade is pressed against the glass pane and a raised position wherein the blade is spaced apart from the glass pane. The invention is characterized in that it comprises means for locking the first end (10a) of the arm (10) in lowered position, which are adapted to change state when a lifting force is exerted on the arm (10), to enable the first end (10a) of the arm (10) to be moved towards the raised position.

Abstract: The invention provides a wiping system of a motor vehicle glass panel, including a wiping blade assembly with a longitudinal main orientation, including a blade of the glass panel blade assembly pressure means on the glass panel, which exert a pression force on the rear end of the blade assembly, and where the pressure means exert on the blade assembly an additional force, where the additional force is produced so as to distribute the pressure of the wiping blade globally symmetrically with respect to the middle in the longitudinal direction of the blade assembly.
